In the form of the disc cutter shown in Fig. 4 thereare threeequally spaced radial openings I3@r in which there are located threecutting elements I 3a." More or less openings and cutting elements maybeused as hereinafterfurther described.`

'I'here are `severalbaflles 2| radially mounted upon the bottom of thedisc 13b, and preferably straddling the 'openings-|32 Thereis a casing22 mounted upon-the underside of the truck vand partially encasing thedisc cutter. |3and terminating at oneside in abaflie23l The bailles 2 I'are adapted to scoop the milled ice and discharge it down over thebaille `23 and throughfthe opening 24. iA bag or pail for collecting themilled ice may be placed beneath the opening 24.

The means forrotating the disc cutter I3 comprises a shaft 25 which isconnected with the cutter and which is rotatively supported bystandvards 26. A worm gear 21' is mounted onthe shaft 25 and meshes witha worm 28 supported upon the standards 26. This worm 281s upon a shaft29 carrying a pinion 30 engaged by a chain 3| also engaging over a gear32. This gear 32 is fixed on a shaft 33 which-is rotatively. mounted instandards 34 and-extends to the'front of the truck. At the front theshaft` 3 3 connects with al gear reduction mechanism 35 indirectlyconnected with the motor of :the truck bya clutch 36. This clutchfisprovided with an 'operating handle 36Vby which it may be engaged and.dis-

engaged as desired.

, Arod or cable 31 connects With theclutch handle 36 at one end and atthe other end with a lever` 38 pivotally mounted intermediately by apintle 39. This lever 38 is disposedadjacent the chute I0 and may beoperated to engage or disengage the clutch. The conventional clutchpedal 40 of the motor vehicle may also be operated from therear of thevehicle bya bell Vcrank 4| which isl pivotally mounted `and whichconnects with a rod or cable 42v extending to a pivotally mounted`lever43 in the vicinity ofthe lever 38. Thevconventional gasaccelerator 44 of the truck is engaged by a lever 45 which is pivotallymounted ona -bracket 46; This lever 45 connectswith a rod or cable 41connectedat another portion with alever 48 arranged in the vicinity ofthe levers 38 and 43.

Upon the side ofthe truck there is an opening 'Y n 49 which aligns witha corresponding opening 50 in the side of the chute I0. A lever 5I ispivotal- The purpose of these slots is to permit the"- It is thuspossible to cut the cake of ice withoutpermitting a core portion to lymounted upon a bracket 52 intermediate of its ends and at one end'isformed with a handle portion 53. The other end connects with a pin 54extending through the openings 49 and 5I] and adapted to engage againsta cake of ice withinthe chute and force the ice against the opposed wallof the chute and so lock and hold the ice in fixed position'.

In Fig. 9 amodified' form of the invention has been disclosed in whichthere is a closedcasing A blower 551s mounted upon the truck anddischarges into one side of the casing 22a and is capable ofpneumatically conveying the milled ice out through a pipe system 56 onthe other` side of the casing 22a. This pipe system extends around and'over one side of the truck. A ybag 51 for collecting ice is adapted tobe engaged upon the end of the pipe 56.`

In Figs. 10 and l1l a. modified `form of disc cutter has been disclosedwhich is substantially identical tothe form previously shown and described'except for'the number of cutting elements. In this form of the4invention there is .a disc I3b'formed'with four radial-openings I3carrangedfat right'anglesand in which-the cutting elements I3aare-disposed. These cutting elements are secured upon anges I 3d byboltsl 20. `l=t`adial bailles 21|' are arranged on the bottom of thedisc |3b'and straddle the openings' I3'. The vdisc 13b hasl a hubportion I3e bindingi together the various sections between the radialopenings |30. A"A t thetop of the hub portion I3`= there isa conicalportionl I3t against which the inner ends of: the'v radial cuttingelements 13* may engage.l v I In Fig. l2 there is another modified formof the invention in'which there is av chute IIIa of greater width thanthat shown in Fig. land which is capable of holdingafull sized cake ofice. In the form. previously describedit is -necessary that the cake oficefbe lsplit in'half.r In the form of vthe invention shown in Fig.' `12the disc cutter I3 is sufficiently large to Vengage across the entirecake ofice Within the chute I 0a. In other re spects this form of the1'invention is identical to the previous forms and the same parts .maybe recognizedby the corresponding numerals.

The operation of the device is as follows: A cake of ice I8 isplacedwithin the chute |01 The lever 43 is moved so that the clutchpedal 40 is pressed in and .the conventional transmission clutch of thevehicle isjdisengaged.' Then the lever 38 is 'moved to move the handle36' and .engage the clutch 36. Rotationswillbe transmitted through thegears 35,l the Vshaft 33, etc., to rotatelthe disc I3., Ifit is desiredto speed up the rotation, the lever 48 maybe moved to cause depressionof the gas pedal 44. Whenthus operated the cake of ice may be milled in.a fverys'hort period of time.

If after, a certain amountof vthe ice'has been collected and it isdesired to delay further milling f for a short while, it is merelynecessary to move Vthe lever 5I so that the pin 54'engages against theside of the cake of ice and locks the cake of l 22a engaged over thebottom of the disc cutter.

ice against the side of the chute. As the ice cannot now movedownwardsthe milling operation will ceasev even though all of lthe milling partsare operating. Y

It is to beun'derstood that .my millingdevice may also bedriven Yby anindependent motor instead of the transmission of the vehicle, also thata suitable weight may be placed on top of the ice when the cake of icebecomes small and dimin- 2,081,001 f i Q V ishes so that its weightlwill not be sumcient to feed it against the rotary cutter.
